Microalgae, known for their land-sparing cultivation and remarkable photosynthetic efficiency, play a crucial role in advancing sustainable development goals. This study explored the use of cost-effective inorganic carbon (the ionic form CO2) organic sources (lactose, primary sugar whey wastewater) to support growth Chlorella Sorokiniana UTEX 1230, improved protein content through nitrogen supply optimization. NaHCO3 proved be more effective than Na2CO3, resulting 3.4-fold increase biomass concentration, with an initial 5 mM HCO3¯ concentration compared basal medium. Further addition 0.75% lactose led 4.05-fold maximum specific rate at 1.28/d, 695.88 mg biomass/L, productivity 250.91 mg/L/d. Nitrogen supplementation greatly increased from 16.41% (250 mg/L NaNO3) 52.95% (1000 NaNO3). These results potential utilizing wastewater bioremediation produce high-value via microalgal cultivation.

Abstract Microalgae are well-known for their role as sustainable bio-factories, offering a promising solution to the global food and nutrition crisis. To clarify potential of Chlorella sorokiniana UTEX 1230 applications, particularly an alternative protein source, study employed mixotrophic cultivation mode with sodium acetate (NaAc) cost-effective organic carbon (NaAc-C) source. Varying levels NaAc-C nitrate-sourced nitrogen were investigated, optimizing effect metabolic characteristics microalgal growth. The designed heterotrophic confirmed ability C. grow on NaAc-C, then cultures, when supported by both CO 2 , exhibited superior growth performance, achieving double biomass concentration compared autotrophic control. addition (750 mg/L NaNO₃) facilitated thorough metabolism enhanced photosynthetic activity indicated 196% increase in pigment levels, which resulted maximum 2.82 g/L 150 mM group. A detailed analysis concentrations over time revealed that higher availability led greater accumulation was degraded support essential life activities under starvation. Therefore, it is suggested supplementing nitrate 3 rd day harvesting 4 th could be strategically implemented yield from 0.17 g/L/d 0.34 g/L/d. These findings offer theoretical guidance further refining this strain use protein.
